This invention aims to provide novel means for catching flies and other insects that are either within or without a room, and, specifically to catch flies or other insects which may 5, crawl up the outside of a screen door or up the inside of a screen door. 7

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of constructionh-ereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows, in vertical section, a portion of a building equipped with the device forming the subject matter of this application;

Figure 2 is a horizontal section on the line 2-2 of Figure 6;

Figure 3 is a vertical section on the line 3-3 of Figure 2;

Figure 4 is a vertical section on the line 44 of Figure 2;

Figure 5 is an elevation showing a portion of a screen door equipped with the device forming the subject matter of this application;

Figure 6 is a vertical section taken through the trap, the door appearing in elevation.

In Figure 1, the numeral 1 marks the wall of a building, the ceiling of a room appearing at 2, and a porch roof at 3. The transom above the door 4 is designated by the numeral 7. An electric lamp 5 may be placed on the ceiling 2 adj acent to the door 4, and an electric lamp 6 may be placed on the porch roof 3, adjacent to the door, although, if there is sufficient light, one or both of the lamps 5 and 6 may be dispensed with, or put out. The screen body of the door is designated by the numeral 8.

A guide plate 9 is held apart from the frame of the door 4, on the inside of the door, but is connected to the frame of the door by a top spacer 10 and by end spacers'll. The construction is such, that, at the lower end of the guide plate 9, there is an entrance opening for insects, which crawl up the inside of the screen body 8 of the door, the en trance opening being marked by the numeral 12 in Figure 4.

The trap embodies a box-like casing, de- 60 noted as a whole by the numeral 14. The body of the casing 14 comprises a metal back plate 15, metal end plates 16, a screen top 17, a screen front 18, and a bottom plate 19 having holes 20. y M

The holes 20 normally are closed by a bottom closure 21, connected by hinges 22 with the back plate 15 and held closed by pivoted latches '23 (of any desired construction) mounted on the end plates 16 of the casing.

Angle brackets 24 are attached to the end plates 16 of the trap casing, as shown in Figure 4, these angle brackets being screwed to the outer surface of the door 4, as disclosed in Figure 5. The casing of the trap is attached additionally, to the door, because the back plate 15 has depending tongues'25 (Figures 5and 6) connected by bolts 26 with a strip 27, thebolts' 26 passing through the screen body 8 of the door 4, the strip 27 and the tongues25 being located on opposite'sides of the screen body 8, as Figure 4 will show.

Main triangular leaders 28, made of wire netting, are secured to the bottom plate 19 of the trap casing, and are spaced apart longitudinally of the casing, as Figure 6 will show. These leaders 28 do not open downwardly through the casing 14, because their lower ends are closed by the bottom plate 19. 7

Each of the leaders 28 has a reduced neck 29 at its upper end. The leaders 28 are connected to flanges 30 (Figures 4 and 6) which project inwardly'from the back plate 15 of the trap. The flanges 30 form, in the back plate 15 of the trap, triangular openings which communicate with the leaders 28, at the back of the leaders. The aforesaid openings register with openings 31 (Figure 4) in the screen body 8 of the door 4. They register, also, with correspondingly shaped openings 32 in a filler 33 secured between the guide plate 9 and the screen 8 of the door 4.

On the downwardly opening closure 21 for the casing 14 are located tapered leaders 34.

. leaders. 3.4- intothe casing 14.

' Referring to Figure 4, it w the flies on the inside ofv thev door'moveup- ,The tapered leaders 34 open downwardly through the closure 19. When the closure 21 is shut-on its hinges 22, the tapered. secondary leaders; 34. are disposed within the. 'c'as ing 14, between the main leaders 28,, as shown in F iguregs '6 and 4. The secondary leaders 34, unlike the main leaders 28, do not-openbackwardl -,;fthrough the rear plate of the casing 14, {but open upwardly into the'casing through the tapered necks at the up per end of the leaders 34. The lower ends of the secondaryleaders 34 are mounted on inclinedf flanges 36,. carried by the. bottom clo sure 21,"t0. be seen in Figures6 and 3 of the drawings, and when the member 21 is closed,

theleaders 3.4 stick up through. holes in the bottom-proper 19 of the casing 14.

In practical operation, referringto Figure 3,. the. flieson the outside of the screen 8 move upwardly as indicated by the arrow'A in Fig 'ure 3 and enter the secondary leaders 34, the

flies passing through the necks 35 oi the ill-be seen that wardly along the screen 8, asindicated'by the arrow B and pass throughthe opening 12, ing-fr'ontof the guide plate 9, the flies passing thence through the openings 32 of the filler .33, and through the openings 31 of: the screen 8, into the main lead'ers 28, the flies passing out of'the leaders 28, into the. casing 14, of the trap, through the necks 29 of the leaders- 28.

The construction is such that thetrap, although located on one side of the door will catch flies which are on either side of the edoor.

The transom 7 will afford the necessary light from the lamp. 5, and the lamp 6, being '5 to V flies conveniently fromin'front of the main leaders '28, the openings 20' are provided. If the operator wishes, he can put any kind conditions, the lamps '6 and 5 are:unnecessary, one or'both of them, of course,can be extinguished: i The operator moves the latches 23 outwardly, thus setting the hinged bottom closure 21 free, sow that itc'an" be swung downwardly. I When the bottom: closure'21'is swung downwardly, the "secondary leaders 3:4 are carried the opening unencumbered. 4 52., :A trap of the class described, comprisinga casingprovided with a leader which any specific bait support, the operator has been left free to support the bait 'n any way that he wishes. "l

Having thus described the invention, what is claimed is: l

1. A trap of the class described, comprising opens through one side of the casing, the casing; being provided with a bottom and the bottom having holes, a hinged closure for one ofthe holes, and a leader carried by the closure and opening through the closure,fthe last-specified leader occupying the other hole when the closure is shut.
